fixurjavainstall: Previous Fuji versions can accidentally wipe `/usr/share/man/man8`
Blast Radius
fixurjavainstallReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects crates.io packages — download data is not available via public APIs for these ecosystems.
Description
Impact
Affects: Anyone who generates the UNIX man pages in Fuji <= 0.8.0 build with the dev crate feature.
Consequences: /usr/share/man/man8 may be entirely removed & re-created without any of the previous entries.
Patches
At the time of writing, no new version has been released on crates.io, due to an unrelated CI/CD publishing issue. Due to the same unrelated publishing issue, no new GitHub Releases version has been released.
Workarounds
Do not run fuji manual on non-dev builds for versions <= 0.8.0.
Additional Information
This bug results from development-only code being accidentally left in for release use.
Previous versions of Fuji are still "safe" to use, provided that you do not run fuji manual.
There is no malicious potential from this, it's just a major annoyance to accidentally remove all your sysadmin man pages.
Affected Packages

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for fixurjavainstall. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update fixurjavainstall to 0.8.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-fq3w-p4fg-mw73 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-fq3w-p4fg-mw73 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-fq3w-p4fg-mw73. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-fq3w-p4fg-mw73 in your dependencies?
O3 detects GHSA-fq3w-p4fg-mw73 across crates.io dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
